Customized Pillow Block Housing Units 鈼?Introduction Pillow block housing units UCT series consists of a UC bearing and a slider bearing seat T. The bearing seat is generally formed by casting, which can be cast from materials such as gray cast iron, ductile iron and cast steel. The bearing seat has a guide groove, and the bearing can adjust the support position of the shaft center by moving radially along the guide groove. The bearing is pre-sealed with a certain amount of lubricating grease, and the user does not need to add lubricating grease before use. The sealed lubricating grease runs inside the shaft, so that the grease inside can provide sufficient and effective lubrication, and it can be long-term without adding grease. The pillow block housing units UCT series has good interchangeability, and it can replace the inner bearing separately when the bearing in the bearing seat is damaged. UCT bearings are mainly used for belt conveyors, conveyor belts and occasions where the center of the shaft needs to be moved. 鈼?Bearing Series The types of the pillow block bearings include UCT200 series and UCT300 series. 鈼?Production Details 鈼?Martempering of bearing rings Martempering means that after the bearing rings is heated and kept at the normal quenching temperature, it is quickly put into a medium with a temperature slightly higher or lower than the M (martensitic transformation temperature) point, stayed for a period of time, and then moved into a medium at room temperature and cooled to room temperature. The use of martempering is to reduce the deformation and cracking of the parts, because the isothermal temperature near the M point can reduce the temperature difference between the center and the surface of the part, and the thermal stress caused by the inconsistent shrinkage on the metal section is greatly reduced. The classification temperature of the bearing ring is below the M point, usually between 120 and 200 掳C. The residence time of the classification temperature is determined by the effective thickness of the bearing rings and the amount of quenching at one time, usually 2~5min. After the bearing steel ring stays at the grading temperature, it is put into 10# and 20# mechanical oil at 30~60鈩?for cooling, and the thin-walled parts can also be air-cooled. After graded quenching, the amount of retained austenite increases significantly, so the cold treatment process should be added. 鈼?ISO9001 standard The ISO9001 standard emphasizes the characteristics of abnormal factors that greatly affect the quality variation, which are sometimes absent in the process, and the direction of influence on the quality variation is determined. Abnormal factors are controllable (can be identified and eliminated). The quality variation caused by abnormal factors is called abnormal quality fluctuation. Since abnormal quality fluctuation can be identified and eliminated, we adopt «strict control». Measures taken to prevent abnormal factors, referred to «precautionary measures» in the ISO 9001 standard, as well as «measures taken to eliminate the causes of potential non-conformities or other potential undesired conditions». 鈼?Tempering of Bearing Rings The heat treatment process of heating quenched steel to a certain temperature and then cooling it to room temperature after holding for a certain period of time is called tempering. Tempering is to reduce the internal stress of quenching and prevent cracking. to stabilize the structure, thereby stabilizing the size and improving the toughness. The tempering process is to load the quenched ferrule into a tempering furnace (usually an air electric furnace with a fan, an oven, an oil furnace and a nitrate furnace), heat it to the tempering temperature, keep it for 2~3 hours, and freely cool it in the air. 鈼?Advantages Our company has a reasonable talent structure, with more than 110 employees, including 19 technical developers with a bachelor degree or above.
